[Ubuntu 16.04] How to install a Arma 3 server

Support Article

You’re going to first start of by updating Ubuntu to ensure the latest bug and security updates are patched.

sudo apt-get update

You will next need to install some dependencies for Arma 3 and steamcmd to use, we will also be installing screen

sudo apt-get install lib32stdc++6 lib32gcc1 screen -y

We advise against using the root user for security reasons, so we will be creating a new user for the server

sudo adduser arma3

The following command needs to still be ran as root to allow your new user to access screen

chmod o+rw /dev/pts/0

Now we can switch to our new user to start creating the server

sudo -i -u arma3

We will now create a new directory for SteamCMD

mkdir ~/steamcmd && cd ~/steamcmd

Start the download of the steamcmd installer by entering the following:

wget http://media.steampowered.com/installer/steamcmd_linux.tar.gz

We can extract the contents of the steamcmd installer simply by entering:

tar -xvzf steamcmd_linux.tar.gz

Running the SteamCMD command line is the next step. Once the extraction has completed we can start with the download of the Arma 3 server files.:


You will then need to login to Steamcmd using a valid steam account (Note this does not need to have Arma installed, Valve recommends using a blank steam account for this)

login myusername

Next we will specify where to install the server:

force_install_dir ./arma3/

Next we will download the Arma 3 Linux dedicated server files:

app_update 233780 validate

We can now exit SteamCMD:


We will now create the directories for the profile files and Arma3.cfg file

mkdir -p ~/".local/share/Arma 3" && mkdir -p ~/".local/share/Arma 3 - Other Profiles"

To launch the server run the following

script /dev/null

screen -S armaserver

cd arma3

./arma3server -name=server -config=server.cfg

You can then exit screen using Control + A + D

[Configuring the server]

You can edit most the server settings in the config file

cd ~/steamcmd/arma3

nano server.cfg
